What API Account name do I enter @ Paypal permissions

[youratcs]

I cant get my site to process credit card payments thru my website payments pro Paypal account. I have tried having my host install the WPP modual and that just crashed my site. They are of help. I believe the problem is that I have another site with a differnent shopping cart which uses that cart API account name. I opened a new WPP account and to complete the activation under API permission, I need to enter the API Account Name for OSCommerce. My hos t is Siteground and they don't have a clue. Paypal lists the following API account names;

 

Partner Name: API Account Name

AsecureCart: info_api1.asecurecart.net

Cart32: paypal_api1.cart32.com

Can anyone help me with the account name for OSCommerce so I can finish activating my WPP account? It would be greatly appreciated as I have been fighting with this for over 6 days now.
